powerpc/book3s64/radix: add support for vmemmap optimization for radix
With 2M PMD-level mapping, we require 32 struct pages and a single vmemmap page can contain 1024 struct pages (PAGE_SIZE/sizeof(struct page)). Hence with 64K page size, we don't use vmemmap deduplication for PMD-level mapping.

dt: Remove booting-without-of.rst
booting-without-of.rst is an ancient document that first outlined Flattened DeviceTree on PowerPC initially. The DT world has evolved a lot in the 15 years since and booting-without-of.rst is pretty stale. The name of the document itself is confusing if you don't understand the evolution from real 'OpenFirmware'. Most of what booting-without-of.rst contains is now in the DT specification (which evolved out of the ePAPR). The few things that weren't documented in the DT specification are now.
All that remains is the boot entry details, so let's move these to arch specific documents. The exception is arm which already has the same details documented.

powerpc: Provide initial documentation for PAPR hcalls
This doc patch provides an initial description of the hcall op-codes that are used by Linux kernel running as a guest (LPAR) on top of PowerVM or any other sPAPR compliant hyper-visor (e.g qemu).
Apart from documenting the hcalls the doc-patch also provides a rudimentary overview of how hcall ABI, how they are issued with the Linux kernel and how information/control flows between the guest and hypervisor.

docs: powerpc: convert docs to ReST and rename to *.rst
Convert docs to ReST and add them to the arch-specific book.
The conversion here was trivial, as almost every file there was already using an elegant format close to ReST standard.
The changes were mostly to mark literal blocks and add a few missing section title identifiers.
One note with regards to "--": on Sphinx, this can't be used to identify a list, as it will format it badly. This can be used, however, to identify a long hyphen - and "---" is an even longer one.
At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

Documentation/powerpc: VAS API Power9 introduced Virtual Accelerator Switchboard (VAS) which allows userspace to communicate with Nest Accelerator (NX) directly. But kernel has to establish channel to NX for userspace. This document describes user space API that application can use to establish communication channel.

powerpc: Provide initial documentation for PAPR hcalls This doc patch provides an initial description of the hcall op-codes that are used by Linux kernel running as a guest (LPAR) on top of PowerVM or any other sPAPR compliant hyper-visor (e.g qemu). Apart from documenting the hcalls the doc-patch also provides a rudimentary overview of how hcall ABI, how they are issued with the Linux kernel and how information/control flows between the guest and hypervisor.

docs: powerpc: convert docs to ReST and rename to *.rst Convert docs to ReST and add them to the arch-specific book. The conversion here was trivial, as almost every file there was already using an elegant format close to ReST standard. The changes were mostly to mark literal blocks and add a few missing section title identifiers. One note with regards to "--": on Sphinx, this can't be used to identify a list, as it will format it badly. This can be used, however, to identify a long hyphen - and "---" is an even longer one. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
